Description/Abstract

Advanced finite element (FE) techniques are used to analyse mechanical stress and strain concentrations in and around an optical fibre (OF) embedded in composite laminates. The models represent many features observed in real materials with embedded OFS. Three general laminate constructions were analysed with the OF at the mid-plane and near the laminate surface. Models represent test coupons used to measure effects of embedded OF on laminate strength in tension and flexure; applied loads and boundary conditions reflect these tests. Failure analysis is performed.
